 The second important battle was fought at Vâlcov, between 27 January and 3 February.The actions of Bolshevik warships (including three "Donetsk"-class gunboats), managed to delay the Romanians for several days, but the ships had to retreat on 3 February due to no longer being able to adjust and correct their aiming, after Romanian artillery destroyed the shore-based Bolshevik artillery observation posts.Later that day, Romanian troops occupied Vâlcov.
